Line 5:
Turbo codes make it possible to increase available bandwidth without increasing the power of a transmission, or they can be used to decrease the amount of power used to transmit at a certain data rate. Its main drawbacks are the relative high decoding complexity and a relatively high [[latency (engineering)|latency]], which makes it unsuitable for some applications.
* For satellite use, this is not of great concern, since the transmission distance itself introduces latency due to the limited [[speed of light]]
Prior to Turbo codes, the best known technique combined a [[Reed-Solomon error correction]] [[block code]] with a [[Viterbi algorithm]] [[convolutional code]], also known as RSV codes. These RSV codes never were able to approach the [[Shannon limit]] as closely as Turbo codes have been able to.
